What is QUANTiC?

The QUANTiC encoder series integrates Renishaw's filtering optics design and interpolation technology to create a high performance, super-compact, digital all-in-one incremental open optical encoder. QUANTiC encoder systems are easy to install with exceptionally wide installation and running tolerances, along with built-in installation and calibration functions. Further diagnostic information can be accessed by using the Advanced Diagnostic Tool ADTi‑100 and ADT View software during installation or for in‑field diagnostics and fault finding. Speeds up to 8 800 rpm can be achieved to meet the most demanding motion control requirements. The QUANTiC encoder offers resolutions down to 50 nm and a wide range of configurations, making optimisation easy and simple. Dynamic signal processing gives improved signal stability to achieve superior performance from your motion control system.
What is RESM40 ring?

RESM40 is a one-piece stainless steel ring with 40 µm pitch incremental graduations marked directly on the periphery, featuring the IN-TRAC optical reference mark. Two versions are available in a wide range of sizes (Ø52 mm to Ø550 mm): ‘A' section rings, which offer an impressive installed accuracy and feature a taper mount system, reducing the need for highly toleranced machined parts and eliminating eccentricity; and ‘B' section thin rings, which have low inertia and mass. Both 'A' and 'B' section rings have a large internal diameter for flexible integration. The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
